'Application med August 22, 1914. serial No. 858,153.

T0 all whom tf/nay concern." y

Be it known that I, RAYMOND T. GILLIS, a citizen of the United States, residing at East McKeesport, in' the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Sad-Irons; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable other skilled in the art to which it appertains to make 'and use the same.

This invention comprehends certain new and useful'improvements in sad irons and has for its primary object to provide a device of this character which will be constructed in such manner that it will be impossible to overheat the iron.

rlhe invention has for another object to provide a device of this character which will be provided with an audible signal to notify the user that the iron is hot enough for use, so that the user will not leave the iron over the fire long enough for the flat surface of the iron to become hot enough toscorch the work.

The invention has for a further object to provide an iron of this character which will be provided with a safety valve whistle adapted to be operated by steam created byl the water within the hollow iron being heated as the iron isl over the fire. A

The invention has for a still further object to generally improve and simplify the construction and operation of devices of this character and increase the efficiency thereof Y without materially increasing the cost of the same.

With these and other objects in view as will become more apparent as the. description proceeds, the invention consist in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and' claimed.

For a 'complete understanding of -my invention, reference is to be had to the following description .and accompanying drawings, in which- Figure 1 is a vertical longitudinal section through the iron, and Fig. 2 is a detail transverse horizontal section on the plane of line 2-2 of Fig. 1.

Referring in detail to the drawings by numerals, l designates the hollow body of the iron to the upper face of which are secured the upstanding supports 2 by means of screws 3 or otherl suitable securing mem- A bers engagedthrough theoutturned lower end o f said upstanding support 2. The upstandmgrsupport 2 serves tosupport the horizontal Vhandle 1 positioned between the (it)A same and s ecuredin position by screws 5 or v other suitable securing members passed through the upper ends of the upstanding supports 2,. and into the opposite endvof said handle 4. y

The hollow body lof the iron is adaptedv to contain water or some other suitable fluid and has a valve opening 6 in thel center of its upper face and upon which is resiliently retained the conical valve 7 mountedV upon the lower enlarged end 8 of the valve stem 9, the upper reduced portion of which extends through and is adapted for sliding movement through the central opening 10 in the top of the spring adjusting cap 11 which has steam escape openings 12 in its upper portion and which is threaded upon the up- `standing circular flange 13 formed on the upper face of the iron body l around the valve opening 6, as will be readily understood by referring to the drawings.

Engaged around the upper portion of the valve stem 9 is a helical springv 14: which has one end engagedagainst the inner face of the upper portion of the spring adjusting cap l1, while its opposite end is engaged against the upper face of the Whistle tube 15, the outer' end ofwhich rests upon the enlarged inner portion 8 of lthe valve stem 9 and the free edge of which is spaced slightly from the upper face of the hollow body 1 of the iron when the valve 7 is in closed position. The valve spring 14: serves to resiliently retain the valve 7 in normal f or closed `position and also serves to retain.

other uid within the hollow body 1 of the iron to such a degree that steam is gen-v erated within said hollow body 1, the steam will work upon the valve 7 to unseat the same and in passing the whistle tube on its way to the air or steam escape openings 12, will ysound an audible signal. adjusting cap 11 is preferably vadjusted so that the valve 7 and whistle tube 15 will be raised by the pressure within the hollow body 1 of the sad ironl when the iron has been suiciently heated but before the same The spring becomes hot enough to scorch the articles with which it may come in Contact during use of the iron. v

`Whi1e I have shown and described the 5 preferred embodiment of my invention, it

said valve opening, a valve adjusting cap,

a valve stem, said valve being mounted on said stem and engaged through the valve adjusting cap, means engaged with said valve stem and said cap for resiliently retaining the valve in closed position, said valve cap having outlet openings formed therein, and a Whistle tubemounted upon said valve stem.

2. An iron comprising a hollow body having a valve opening in itsl upper portion, a threaded upstanding flange `formed with the bodyaround the valve opening, a valve positioned against said opening, a valve stem for said valve, -said valve stem having an enlarged portion, a Whistle tube mounted upon the enlarged portion of the valve stem, a springengaged around said valve stem and resting upon the Whistle tube to retain said tube and valve in normal position, a valve spring adjusting cap threaded upon said flange and bearing against said spring,. said Vvalve stem being engaged through said valve spring adjusting cap, said cap having escape openings for steam passing from the hollow body and traveling past the Whistle tube to sound an audible signal, and a handle for said iron.

In testimony whereof I aiX my signature in presence of two Witnesses.
